7.0 Overview
A system which includes an SSPA can be managed from a remote computer over a
variety of remote control interfaces (see
Figure 7-1
).
The parallel port on SSPA unit provides a simple form of remote control. There are 10
“dry” Form-C relay contacts for remote monitoring and six (6) galvanic isolated inputs
for remote control commands. Parallel interface is always enabled, and does not re-
quire any special settings to operate.
Serial interface supports both RS232 and RS485 standards. The control protocol sup-
ports two formats: Normal serial protocol (as detailed in
Section 7.2
) and ASCII based
protocol suitable for HyperTerminal applications (see
Section 7.5
). Serial interface is
equipped with overvoltage and overcurrent protection and benefits from full galvanic
isolation from the chassis ground for extra protection.
The Ethernet interface supports multiple communication standards which can be used
exclusively or simultaneously depending on the selected setting:
•
IPNet - UDP encapsulated Normal serial protocol (
Section 7.6.10
);
•
SNMP V1 with support of SNMP traps (
Section 7.6.2
);
•
HTTP web interface (
Section 7.6.1.3
);
